core/hash/sha256 - Verilog implementation of the SHA-256 cryptographic hash function

Age	Commit message (Collapse)	Author
2015-07-17	Fixed state restore testcase in core testbench. Fixed the double block test ↵	Joachim Strömbergson
	case to really test the core. Added data valid task.
2015-07-17	Minor cleanup.	Joachim Strömbergson

2015-07-17	Removed the address defines not needed.	Joachim Strömbergson

2015-07-17	Since state is digest having separate addresses for writing state is ↵	Joachim Strömbergson
	superflous. Captain slow.
2015-07-17	Added top level test case for restore state and continue hashing. Test OK.	Joachim Strömbergson

2015-07-16	Adding a task to dump the H state.	Joachim Strömbergson

2015-07-16	Adding test case for state restore.	Joachim Strömbergson

2015-07-16	Added logic to write state into the state registers. Simplified the state ↵	Joachim Strömbergson
	write interface to a common data port.
2015-07-16	The digest is the complete state so we only need to be able to write back ↵	Joachim Strömbergson
	state. The state addresses are still readable though.
2015-07-16	(1) Adding addresses to be able to read and write the internal hash state ↵	Joachim Strömbergson
	from the API. (2) Bumped version to reflect the changes to the API. (3) Added ports for state access in the core module and connected them in the top level wrapper.
2015-03-31	Remove wishbone testbench code, because we no longer have the verilog.	Paul Selkirk

2015-03-31	Revert streamlined wrapper, and don't delay register reads.	Paul Selkirk

2015-03-17	Rearrange cores.	Paul Selkirk

2015-03-11	Removed the wishbone wrapper we don't use.	Joachim Strömbergson

2014-11-07	Changed to asynch reset.	Joachim Strömbergson

2014-11-06	Fixed nits found using verilator linter. Removed trailing whitespace.	Joachim Strömbergson

2014-05-16	Adding helper functions for printing digest. Adding testcase for message ↵	Joachim Strömbergson
	with 1000 blocks.
2014-04-01	Updating sha256 python model with NIST dual block test case and test case ↵	Joachim Strömbergson
	with huge message. Disabling verbose mode.
2014-03-17	Removed redundant flag reset wires.	Joachim Strömbergson

2014-03-16	Adding self resetting init and next flags. Updating TBs to not reset the ↵	Joachim Strömbergson
	flags. Fixing clock parameter naming.
2014-03-15	(1) Updated interface to new std. (2) Added missing input designation in ↵	Joachim Strömbergson
	tasks. Now simumaltion with ModelSim works.
2014-02-26	Removed the positions of W no longer needed.	Joachim Strömbergson

2014-02-26	Changed the python model to use a sliding window for W.	Joachim Strömbergson

2014-02-23	Fixed compile problems due to copy crime.	Joachim Strömbergson

2014-02-23	Moved wmem update logic to a separate process.	Joachim Strömbergson

2014-02-22	Updated testbenches to the new sliding window W-mem.	Joachim Strömbergson

2014-02-22	Changed W-memory into sliding window. This also affected interface and ↵	Joachim Strömbergson
	integration in the core.
2014-02-19	Adding a Python model for the SHA256 core.	Joachim Strömbergson

2014-02-19	Adding a testbench for the Wishbone wrapper.	Joachim Strömbergson

2014-02-19	Adding a testbench for the SHA256 top level wrapper.	Joachim Strömbergson

2014-02-19	Adding a testbench for the SHA256 core.	Joachim Strömbergson

2014-02-19	Adding a testbench for the w memory module.	Joachim Strömbergson

2014-02-19	Adding a Wishbone wrapper for the SHA256 core.	Joachim Strömbergson

2014-02-19	Adding top level wrapper for the sha256. This wrapper provides a simple ↵	Joachim Strömbergson
	memory like interface.
2014-02-19	Source for the main part of the sha256 core.	Joachim Strömbergson

2014-02-19	Adding the W memory including scheduler and expansion functionality.	Joachim Strömbergson
